A radically different approach, inspired by the new APS-C Sigma 17-35 F 1.8 lens.

My ideal camera would be a Fuji X20 with a tweaked sensor, but a 27-95 (3.5 X) F1.8 constant aperture lens. Make it weather proof and with a tilt LCD and I'm sold! And maybe some more information in the optical viewfinder.
